BRICK-KILN.

SPECIFICATION forming part of Letters Patent No. 347,650, dated August 17, 1886.

Application filed February Q4, 1886. Serial No. 193,051. (No model.)

To all whom it may concern:

Be it known that I, GEORGE W. SHAKER, a citizen ofV the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Brick-Kilns; and I do vhereby declare the following to be a full, clear,` and exact description of the invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relatesto that class of brickkilns known as the Vingard system.

The object of my invention is to improve that construction; and t0 that end the nature of my invention consists of constructions and combinations, all as will hereinafter rbe described in the specification, and' pointed out in the claims, reference being had to the accompanying drawings, in which- Figure l represents a front elevation of the kiln; Fig. 2, a side elevation with upper part of kiln broken away; Fig. 3, a horizontal section of the furnace, taken on line y y, Fig. 5, Fig. 4, a top plan of the furnace; Fig. 5, a vertical section taken on line z z, Fig. 3; Fig. 6, a section on line s s, Fig.

The kiln A is the same as those commonly used, except at the points where the furnaces are attached, and at those points is formed an abutment, a, having au eye, a', and forming one of the sides of the eyes'a2 and c3. The eye c is placed at the center of the rear of the furnace, and the abutment is inclined rearwardly from the eyes, so that the name striking against it will be equally divided among the eyes. The rear ends, b, of the side walls, B', of the furnace B are inclined in the samemanner as the abutment, to form the side or outer Walls of the eyes or and a3. In these endsb are the sight-holes b. At the angle formed by the junction of each of the parts B and b are air-supplying passages b2 and b3, each having an inlet-opening, b4, a vertical passage, If", and an exit-opening, b, which projects air across the furnace tothe eyes a and {t3-that is to say, the passage b2 projects air in the furnace inthe direction of eye a3, and the passage b3 projects air in the direction of eye a2. If it be desired to project more of the products of combustion into one eye-say eye a2- than in the other-say eye aS-then the passage b is closed. This closure will cause the air passing through passage b3 to deflect the products of combustion into eye a?. The main or top arch, B2, of the furnace is sprung from the walls B', and its rear end rests upon the abutment a, which projects at the side slightly above the arch, as shown in Figs. 4 and 5. The side arches, B3 and B4, for the eyes a'l and c3, are sprung from the curved part b of the wall to the curved part of the abut,- menta, so that when placed together the three arches will support each other and make a stronger top or arch for the furnace than has heretofore been made. A distributing-vault, B5, is also formed in the back part of the furnace by the arches, the parts b, and the front wall of the kiln, so that the products of combustion can be evenly distributed to the eyes. The passages b`Z and lfi are formed in the forward part of this vault, and the air passing upwardly through them is heated by the pro- Aducts of combustion before passing into the upper part of the vault.

As before stated, the top of the abutment projects above the arches, so that an interme diate post, C', can be placed thereon to assist posts C in supporting the roof. This could not be done heretofore, because the posts marked C would rest upon the arch, which would not be strong enough to support the post and superincumbent roof.

I am aware that a furnace provided with a rear wall which rests against the wall of the kiln and having a concave face presented to the furnace, and eyes in said rear wall, is old, and therefore make no claim to that form.

My device is provided with an abutment resting against the rear Wall of the furnace, and presents a convex face to the furnace, for the purposes hereinbefore set forth.

l. In a brick-kiln, the combination, with the front wall having the abutment with conveX face fronting the furnace, of eyes a', ai, and a3, and the furnace, substantially as described.

2. In 4a brick-kiln, the combination, with the front wall having the abutment c, and eyes a', ai, and a3, of the furnace having its side wall curved at the rear ends, and the side arches springing from the curved ends and abutment, and the rear ends resting upon the main arch, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
